In example 1, as shown in (B) of the Fig. 1 as schematic partial end view, by using bonding agent (not shown), integrated circuit 50 is attached to the outer surface of secondary battery cell 20。So, wiring abnormal detection circuit 60 is connected to the abnormality detection wiring set by secondary battery cell 20 or shielding line 66。Shielding line 66 is continuously formed on the outer surface of secondary battery cell 20 from integrated circuit 50。Specifically, shielding line 66 is formed by active shielding, and protects voltage to be applied in this。More specifically, film 65 from integrated circuit 50 by the outer surface of lamination continuously to secondary battery cell 20, the shielding line 66 being connected to integrated circuit 50 at terminal part (pad portion) 64C place is formed on film 65 by silk screen print method。Afterwards, whole it is laminated with outer membrane 67。There is provided opening portion 68A and 68B to outer membrane 67, and terminal part (pad portion) 64A and 64B is in the bottom-exposed of opening portion 68A and 68B。Then, not shown in (B) of wiring 58(Fig. 1) it is attached to terminal part 64A, and not shown in (B) of wiring 48(Fig. 1) it is attached to terminal part 64B。
As shown in Fig. 2 of the block diagram as wiring abnormal detection circuit 60, wiring abnormal detection circuit 60 includes signal generating circuit 61, comparison circuit 62 and "AND" circuit 63。It should be pointed out that, Fig. 2 illustrates the shielding line 66 of three, but the quantity of the line of shielding line 66 is not limited to this。From signal generating circuit 61, predetermined voltage is applied to shielding line 66。
After complete assembled battery group 10, various types of information (data) initialize。In other words, will cause that identification information of all of secondary battery cell 20 etc. is corresponding with the secondary battery cell 20 position in housing 17, and corresponding relation is stored in storage device 92 by control circuit 90。Alternately, the identification information etc. of all of secondary battery cell 20 is stored in storage device 92 by control circuit 90 based on polling system。In the memory cell 53 of each integrated circuit 50, prestore identification information。Then, under the control of control circuit 90, the memory cell 53 of each integrated circuit 50 stores individual information。In addition, under the control of control circuit 90, " information that integrated circuit does not remove will be represented from secondary battery cell " (hereinafter, it is called " non-remove information ") it is stored in the mark region of memory area 52 of integrated circuit 50, and the data that write is suitable are made in the error detection bits region of mark region。The non-information that removes also is stored in the storage device 92 of control circuit 90。
When integrated circuit 50 is intended for removing from secondary battery cell 20, it is necessary to remove outer membrane 67, then have to remove shielding line 66 and film 65。Under such operation, shielding line 66 inevitably leads to disconnect or short circuit, and shielding line 66 enters nonconducting state or short-circuit condition。Therefore, cause the change being imported into the voltage of the comparison circuit 62 of wiring abnormal detection circuit 60 via shielding line 66, and cause the change of the output of "AND" circuit 63。Thus, wiring abnormal detection circuit 60 can detect abnormal wiring。So, the signal processing unit 51 of integrated circuit 50 detects the change of the output of "AND" circuit 63 and would indicate that the abnormal information of wiring that has been detected by (in other words, representing the information that integrated circuit 50 has removed from secondary battery cell 20) is stored in memory area 52。Alternately, when detecting device detects that integrated circuit 50 removes from secondary battery cell 20, memory area 52 stores the information representing that integrated circuit 50 has removed from secondary battery cell 20。In other words, be stored in memory area 52(specifically, mark region and error detection bits region) in data (non-remove information) be deleted or rewrite。
Control circuit 90 based on the positional information of the secondary battery cell 20 of housing 17 with predetermined time interval, specifically send for inquiring about the order whether integrated circuit 50 has removed from secondary battery cell 20 to the integrated circuit 50 set by secondary battery cell 20 via telecommunication circuit 93 and wiring 48, and for inquiring about the order of identification information etc.。Receive the information during the signal processing unit 51 of the integrated circuit 50 of this order sends the identification information etc. being stored in memory element 53 to control circuit 90 and is stored in the mark region of memory area 52。With non-, whether identification information etc. and the control circuit 90 of the information being stored in the mark region information to being stored in mark region that receives remove that information is corresponding to be investigated。So, when the information in being stored in mark region not with non-remove information corresponding, in other words, integrated circuit is not over certification, then determine that integrated circuit 50 is the integrated circuit removed from secondary battery cell 20, and provide warning etc. to the user using set of cells 10。Depend on the circumstances, stop the output from set of cells 10。Additionally, when the information in being stored in mark region with non-remove information corresponding, whether received identification information etc. is mated with the identification information etc. being stored in storage device 92 and is investigated by control circuit 90。It should be pointed out that, the coupling of identification information etc. or do not mate can be investigated before the information being stored in mark region is investigated。All secondary battery cell 20 are sequentially performed such operation and process。Then, do not mate in identification information or identify information matches but in the unmatched situation of individual information, in other words, in the invalid situation of certification, the secondary battery cell 20 that control circuit 90 is determined in set of cells 10 is phonily substituted, and to using set of cells 10 user's to provide warning etc.。Depend on the circumstances, stop the output from set of cells 10。
When integrated circuit 50 removes from secondary battery cell 20, be stored in memory area 52(specifically, mark region and error detection bits region) in data (non-remove information) be deleted or rewrite。It is therefoie, for example, the information (data) being stored in memory area 52 is investigated by control circuit 90, thus can reliably determine that integrated circuit 50 removes from secondary battery cell 20 as mentioned above。
It addition, control circuit 90 and integrated circuit 50 set by each secondary battery cell 20 not only store identification information and also store individual information, for instance, give identifier and the authentication number of secondary battery cell 20。It is thus possible to be easily identified each in secondary battery cell 20 and to easily and reliably determine that whether secondary battery cell is the regular secondary battery cell of certification。
Generally, when there is certain value or smaller value when the discharge voltage of secondary battery cell 20, stop the output of the electric power from set of cells。But, even if in this case, secondary battery cell 20 also has the enough electric power for driving control circuit 90 or integrated circuit 50, therefore, is not result in problem。But, if set of cells keeps this situation, secondary battery cell 20 can lose the enough electric power driving control circuit 90 or integrated circuit 50 for a long time。In this case, it is only necessary to performed the initialization of various information (data) in the charging of set of cells and set of cells by the manufacturer etc. of set of cells。
In example 1 or example 2 to the example 12 that will be described below, set of cells 10 can apply to power consuming device, for instance, electric automobile (includes hybrid vehicle), golf cart, electric motor car, battery-operated motor cycle, electric assisted bicycle and railcar。In other words, power consuming device includes: include the set of cells 10 of multiple secondary battery cell 20, and each secondary battery cell 20 includes the integrated circuit 50 with the measurement function to battery status measurement。So, set of cells 10 can discharge to drive conversion equipment set by above-mentioned power consuming device (specifically, for instance, motor) and by powering to electric power is converted driving force, and the regenerated energy from this device can be used to be charged。It should be pointed out that, these power consuming devices include, it may for example comprise the controlling device and perform the control device controlling relevant information processing to power consuming device based on the information about secondary battery cell 20 of the instruction of residual capacity of battery。
Owing to providing the abnormal wiring abnormal detection circuit detected of wiring in example 1, the integrated circuit set by secondary battery cell can be reliably detected remove from this secondary battery cell, and be reliably prevented this integrated circuit and for another secondary battery cell or be attached to another secondary battery cell。It addition, in order to determine the set of cells being installed to power consuming device is for whether this power consuming device can use safely, owing to this integrated circuit stores identification information, it is possible to easily and reliably the secondary battery cell set by set of cells is authenticated。In addition, owing to adopting so-called cascade connection system as the connection system of integrated circuit 50 and sequentially integrated circuit to be authenticated in example 1, so the identification information etc. of all of secondary battery cell in set of cells can be known by a small amount of wiring of use, without complicated wiring。For this reason, whole set of cells can simplify wiring, and the quantity of junction point with control circuit can be reduced, thus realizing the raising of the reliability of set of cells。
Depend on the circumstances, offer memory area 52 be provided or together with memory area 52, fuse (or circuit breaker) can be disposed in the inside of integrated circuit 50 electric power input side or integrated circuit 50, for instance, signal processing unit 51。So, when connecting up abnormal detection circuit 60 and detecting that wiring is abnormal, integrated circuit 50 fuses (or disconnection) fuse (or circuit breaker)。Thus, disable integrated circuit 50, and reliably the integrated circuit 50 set by secondary battery cell 20 can have been removed from secondary battery cell and detect, and prevent integrated circuit 50 to be attached to another secondary battery cell。
